BOAT.

SPECIFICATION forming part of Letters Patent No. 603,469, dated May 3,1898. Application filed September 20, 1897. Serial No. 652,306. (nomodel.)

- ments in Boats; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it-appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in boatsespecially designed for small pleasure-boats; and it consists in theconstruction and arrangement of parts hereinafter fully set forth, andpointed out particularly in the claims.

The object of the invention is to provide'a boat which may be propelled.by oars or by means of a sail in which the arrangement is such as toprevent the boat from sinking or capsizing, and a further arrangementwhereby the rocking of the boat through the movement of the occupants orthe motion of the water is obviated. This object is attained by theconstruction illustrated in the'accompanying drawings, in which Figure 1is a perspective of my improved boat. Fig. 2 is a side elevation of thesame. Fig. 3is a transverse section on line 3 3 of Fig. 2. Y

Referring to the letters of reference, A designates the hull of theboat, which may be of any suitable form and constructed of any suitablematerial. This hull is of the closed-deck pattern, whereby it isrendered air-tight and therefore insured against sinking. Upon the deckof the hull is a low rail 1), which rises slightly above the deck and.serves to prevent articles from sliding from the rounded face thereof.Rising from the deck" at each end is a vertical standard 13.. Thesestandards are provided at their upper ends with a suitablejournal-bearing a.

O designates a supporting-frame,which consists of the longitudinal siderails D and the cross-rails D, connecting the ends thereof. Secured tothe longitudinal center of the crossrails D are the short shafts orpintles c, which 'upon the frame 0.

are journaled in the bearing a, carried by the standards B, whereby theframe 0 is pivoted above the hull.

Depending from the outer ends of the crossrails D, which project beyondthe sides of the hull, are the vertical bars E, whose upper ends arefirmly secured to said cross-pieces and whose lower ends are providedwith a vertical slot 6. Extending'longitudinally of the hull, on eachside thereof, are the hollow ballast-floats F, which are open at eachend, so as to permit a flow of water therethrough. These floats areprovided in their opposite ends with a short shaft f, which is journaledin the vertical slot in the lower ends of the depending bars E. Theseballast-floats are made of light buoyant material and are adapted to besubmerged'to about half their depth,

as shown in Figs. 2 and 3, and are so mounted in the depending bars E asto enable them to revolve and to rise and fall with the action of thewater. .7

The frame 0 is designed to support the occupants of the boat and isprovided with suit able seats Gr, mounted on said frame, and which maybe located at any desired point. When seated, the feet of the occupantwill rest upon the deck of the hull within the rail b.

The boat is designed to be driven by a sail attached to a mast, (notshown,) which may be stepped in the hull at any desired point, or saidboat may be propelled by means of oars, the locks for which may bemounted It will be seen that while the hull of the boat and the frame 0are united by means of the pivoted connection between them the hull ispermitted to sway from side to side, as shown by dotted lines in Fig. 3,while said frame remains practically horizontal, so that the rockingmotion of the hull is not imparted to the frame upon which the occupantsare seated. It will also be seen that'by means of the ballast-floatsupon each side of the hull, which are partly filled with water, a suddentilting of the frame C to either side is obviated, owing to the factthat said frame is pivoted to the hull A, and in order to depress oneside of the frame the opposite side must rise. The weight of the waterin the float prevents this action of the frame, as the float cannot 10for cause it to rise and fall in the slots 6, so

that the supporting-frame is but little affected by any disturbance ofthe surface of the water.

The boat because of the air-tight feature of its hull is prevented fromsinking, and be- I 5 cause of the ballast-floats on each side thereof itcannot be capsized. The supportingframe may be of light metal bars andmay be of such construction as to permit of properly mounting oarsthereon, so as to propel 20 the boat by this means, such changeinvolving no departure from the spirit of my invention.

Having thus fully set forth my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. In a boat of the character described, the combination with the hull,of the supportingframe mounted on the hull and carrying the seats forthe occupants of the boat, the hollow ballast-floats open at each endpivoted to the bars depending from said supportingframe and adapted torevolve.

2. In a boat of the character described, the combination with the hull,the standards rising from the deck thereof, the supportingframepivotally mounted on said standards and having the four depending barsprovided with slots in their lower ends, and the hollow ballast-floatshaving, an opening therethrough and journaled in said slots.

In testimony whereof I allix my signature in presence of two witnesses.
